Other claims from this paper (10)
- Observation Rice organs responded differently to nitrogen supply, and responses varied by growth stage.
- Intervention effect Strong, less persistent nitrogen supply at tillering promoted leaf blade dry matter assimilation and enlarged leaf area.
- Observation After internode elongation, more dry matter accumulated in rice stems than leaf blades.
- Intervention effect Manure top dressing after internode elongation produced large and healthy rice ears.
- Intervention effect The stage-specific nitrogen treatments favored rice growth and yield under the experimental conditions.
- Intervention effect Strong but less persistent nitrogen supply accelerated nitrogenous material translocation in rice.
- Intervention effect Less intense but persistent nitrogen supply retained more nitrogenous material in rice leaf blades.
- Observation A slower persistent nitrogen supply at tillering was associated with high rice yields.
- Observation A moderate persistent nitrogen supply at panicle differentiation was associated with high rice yields.
- Recommendation Fertilization should regulate nitrogen supply differently for different soil types.
